The required code is highly dependent on your hardware. 
Check out termcap, terminfo, tgetent, tput, and other such entries in your
manual.
In fact, just browing through /etc/termcap, or /usr/lib/terminfo/*src, will
show you that the code sequences you seek are quite variable.

Your system's C libraries give you tools to find the codes for any
given terminal; you then incorporate them into your code so as to be
device-independent.
